Orienting tubing hanger apparatus

ABSTRACT

A tubing hanger for suspending multiple tubing strings is seated in a subsea wellhead or casing hanger, being properly oriented with respect to a running tool by means of which the tubing hanger is lowered from a drilling vessel to seat in the casing hanger. The running tool is properly oriented relative to a blowout preventer stack previously oriented with respect to a guidance system as a reference point, the guidance system extending from the subsea floor to the drilling vessel, resulting in the multiple string tubing hanger being properly oriented with respect to the guidance system for subsequent appropriate connection with a Christmas tree, or other apparatus, to be lowered down the guidance system, which it also uses as a reference point, thereby properly relating the Christmas tree to the multiplicity of passages in the tubing hanger. The tubing hanger is releasably secured to the wellhead or casing hanger through mechanical manipulation of the running tool after the tubing hanger has been oriented with respect to the blowout preventer and guidance system, the running tool being released from the tubing hanger for elevation to the drilling vessel. Thereafter, when desired, the running tool can be relowered and reconnected to the tubing hanger to release it from the casing hanger and elevate it to the drilling vessel.

Jvvewrbe BENTON]: .BAVz/GA/ PATENTEDsEP" 5 m2 SHEET l 0F 5 13v VE/V roeBewro/vI'. B0066 ORIENTING TUBING HANGER APPARATUS The present inventionrelates to subaqueous well bore apparatus, and more particularly toapparatus including a multiple string tubing hanger to be set and sealedin a wellhead or casing hanger.

Apparatus has been used for suspending multiple strings of tubing from atubing hanger seated in a subsea casing hanger or wellhead, the tubinghanger and tubing strings being oriented relative to a reference point,such as the guidance system or structure disposed at the subsea floor,which includes a guide base, guide posts or columns extending upwardlyfrom the base, and cables or wirelines secured to the posts andextending upwardly through the water to the drilling vessel thereabove.With some prior apparatus, to properly orient the tubing hanger withrespect to the guidance system, a separate round trip is requiredbetween the vessel and subsea floor to run-in and retrieve a specialorienting bushing. With other prior apparatus, a mechanical tubinghanger incorporates a spring loaded dog which fits into a slot in awellhead housing, which requires prior orienting of the wellhead housingwith respect to the guidance structure, presenting decided difficultiesand disadvantages.

The aforenoted disadvantages are overcome with apparatus embodying thepresent invention. Proper orienting of the tubing hanger relative to theguidance system, or other reference point, is secured without thenecessity for making additional round trips between the drilling vesseland subsea floor. In fact, only a single trip is required to run-in thetubing hanger, orient it properly relative to a known reference point,and to seal and lock the tubing hanger in its associated casing hanger.Moreover, it is unnecessary to orient the wellhead with respect to theguidance system and then interrelate the tubing hanger to the wellhead.Instead, the tubing hanger is .oriented with respect to another device,such as a blowout preventer stack, guided into position by the guidancesystem. More specifically, the running too] for lowering and landing thetubing hanger in place serves as an intermediate agency for orientingthe tubing hanger with respect to such other device. The tubing hangeris attached to the running tool in a known relationship thereto, therunning tool then being appropriately related to the other device, suchas the blowout preventer stack, resulting in the tubing hanger beingproperly angularly related to the guidance system.

Because of the foregoing features, the multiple string tubing hanger issimpler than corresponding devices, of reduced size, and less costly tomanufacture. The performance of all necessary functions with a singleround trip, and setting and sealing the tubing hanger in an associatedcasing hanger in proper oriented relation to a known reference point,effects considerably savings in rig time and expense. The portion of theapparatus that locks the tubing hanger in the casing hanger alsomaintains an effective and efficient seal of the tubing hanger againstthe casing hanger.

The tubing hanger can be readily unlocked or unlatched and released fromthe casing hanger whenever desired, and elevated to the drilling vessel.If difficulty is encountered in unlocking the tubing hanger, theapparatus embodies a safety feature that enables the tubing hanger to beforcibly released from the casing hanger.

This invention possesses many other advantages, and has other purposeswhich may be made more clearly apparent from a consideration of a formin which it may be embodied. This form is shown in the drawingsaccompanying and forming part of the present specification. It will nowbe described in detail, for the purpose of illustrating the generalprinciples of the invention; but it is to be understood that suchdetailed description is not to be taken in a limiting sense.

As illustrated in the drawings, a multiple tubing string hanger 10 is tobe set in sealed relation in a casing hanger 11 disposed within a casinghanger body 12 suitably supported, as through other casing hangers 12a,12b, in a housing 13 extending into a well bore 14 drilled into aformation underlying the floor F of an ocean, or other body of water. Asis known in the art, the housing 13 and the various casing hangers l1,12 supported thereby are secured to a guidance structure 15 of aguidance system, in a known manner. This guidance structure includes abase 16 having guide posts 17 extending upwardly from its comer portionsand to which are secured cables or lines 18 extending upwardly throughthe water to a drilling vessel (not shown) floating in the water. Ablowout preventer stack 19 is disposed at the lower end of a marineriser 20 extending upwardly to the drilling vessel, this blowoutpreventer stack being suitably secured, as by a coupling 21, to aconnector 22 suitably attached to a casing hanger body 12b supported, ina known manner,

in the housing 13 (FIG. 2). This connector may be of any suitable type,for example, being of the hydraulic type illustrated in US. Pat. No.3,32l,2l7. A suitable seal ring or gasket 23 effects a seal between theupper end of the connector and the lower end of the blowout preventerstack, another seal ring 24 effecting a seal between the casing hangerbody 12b and the connector 22.

The connector 22 occupies a known position with respect to the guidancestructure 15, being moved downwardly with the blow-out preventer stack19 toward the casing hanger body 12b along the guide lines 18. Theconnector has a guide frame 25 suitably secured thereto, the outer endsof which are attached to guide sleeves 26 having lower downwardlyflaring funnels 27 secured thereto, and being slidable along the guidelines 18 and then over the guide posts. The connector has a longitudinalslot or groove 28 disposed therein which has a known orientation withrespect to the guide posts '17. It is with respect to this groove 28that the tubing hanger is to be oriented (FIG. 3), so that the two ormore longitudinal passages 29, 30, 31 extending through the tubinghanger body 39 will bear a known orientation or angular relationrelative to the groove 28 in the connector, and consequently, withrespect to the guide lines 18 and guide posts 17 of the guidance system15, the orientation being accomplished with the structure and in themanner described hereinbelow.

A plurality of concentric casing strings 35a, 35b, 350 are connected attheir upper ends to concentric casing hangers 12a, 12, 11 in stackedrelation and appropriately sealed against the casing hanger body 12b.The uppermost casing hanger 11 is the one on which the tubing hanger 10is to seat and against which it is to be sealed, this casing hangerhaving a suitable downwardly tapering hanger seat 36 and an internallock groove 37 thereabove, the upper side 38 of which tapers in adownward and outward direction.

The tubing hanger 10 includes a main body 39 having the plurality oflongitudinal passages 29, 30, 31 extending therethrough. The lower endof this body is connected by means of a swivel 40 to a landing ring 41having a downwardly tapering seating surface 42 adapted to engage thecompanion seat 36 in the casing hanger 11. The ring 41 has a pluralityof circumferential grooves 43 therein receiving elastomer seal rings 44adapted to bear and seal against the casing hanger seat 36. It alsoincludes circumferential internal grooves 45 containing seal rings 46sealing against the periphery of the lower portion of the tubing hangerbody 39. i

The swivel 40 interconnects the tubing hanger body 39 and landing ring41, permitting the hanger body to rotate relative to the landing ring.As specifically illustrated, the swivel includes a lower body member 47threadedly secured to the body 39 and having a downwardly facing raceway48 opposed to an upwardly facing raceway 49 in the landing ring, therebeing suitable ball baring elements 50 between and rideable in theopposed raceways. The landing ring 41 has an upwardly extending skirt 51encompassing the lower portion of the lower body member 47 and receivingthe outer portion of an inherently expansible retainer ring 52 in aninternal groove 53, which also extends partially into an external groove54 in the lower body member. It is apparent that the retainer ring 52prevents the landing ring 41 from shifting longitudinally with respectto the hanger body 39 and its lower member 47, while permitting rotationof the hanger body and lower member relative to the landing ring 41 whenthe latter is engaged with the casing hanger seat The lower body member47 also carries a plurality of circumferentially spaced lock dogs 55extending through circumferentially spaced radial slots 56 in the lowerbody member and slidable radially therein. The outer portions of thedogs are receivable within the internal lock groove 37 in the casinghanger 12 and with the upper downwardly and outwardly inclined cam faces57 on the dogs engageable with the companion upper cam face or side 38of the groove. Outward movement of each dog is limited by engagement ofits upwardly directed terminal member 58 with the inner surface 59 ofthe lower body member above the slots 56, the dogs being shiftableradially inwardly to the extent limited by their engagement with theperiphery of the tubing hanger body 39. The dogs also have downwardlyand inwardly inclined external tapered surfaces 60 engageable with anupper tapered surface 61 on the casing hanger to be cammed radiallyinwardly thereof during lowering of the tubing hanger body 39 withrespect to the casing hanger 11, as described hereinbelow.

The dogs 55 are expandable outwardly as a result of downward shifting ofa cam actuator sleeve 62 surrounding the tubing hanger body, thisactuator sleeve having a lower portion provided with a downwardlytapering expander surface 63 adapted to move behind the dogs or lockelements 55 and engage companion tapered expander surfaces 64 therein.The cam actuator sleeve 62 is longitudinally shiftable relative to thetubing hanger body 39, but is non-rotatable with respect thereto byvirtue of an orienting dog or key 65 extending through a slot 66 in thecam actuator sleeve and which is also received in a longitudinal grooveor keyway 67 in the tubing hanger body, this key being secured to thebody by one or more cap screws 68. The orienting dog or key is securedto the tubing hanger body in a known and predetermined angularrelationship relative to the longitudinal passages 29, 30, 31 throughthe hanger body.

The cam actuator sleeve 62 is shiftable longitudinally of the tubinghanger body 39 by an actuator sleeve 69 that encompasses the upperportion of the hanger body 39 and which is threadedly secured to anupper actuator ring 70 having an inwardly extending portion or flange 71overlying the upper end 72 of the hanger body. Downward movement of thisactuator sleeve 69 along the body 39 is prevented by the flange 71engaging the upper end 72 of the tubing hanger body; whereas, its upwardmovement is prevented by engagement of an upwardly facing shoulder 73 onthe actuator sleeve with a shear ring 74 encompassing the body andsecured thereto by one or more shear pins or screws 75 extending throughthe ring and threaded into companion bores in the body. This shear ringis initially spaced downwardly from a downwardly facing shoulder 76formed on and provided by an external flange 77 on the upper end of thetubing hanger body. Thus, the actuator sleeve 69 is prevented fromshifting longitudinally in both upward and downward directions relativeto the tubing hanger 39, but is capable of rotat ing with respectthereto. Such rotation will effect longitudinal shifting of the camactuator sleeve 62 along the tubing hanger body 39 by virtue of athreaded interconnection 78 between the lower portion of the actuatorsleeve and the upper portion of the cam actuator sleeve. As noted, theactuator sleeve 69 has external right-hand threads 79 thereon meshingwith companion internal right-hand threads 79 thereon meshing withcompanion internal right-hand threads 80 on the upper threaded headportion 81 of the cam actuator sleeve. Thus, right-hand rotation of theactuator sleeve 69 will shift the cam actuator sleeve 62 longitudinallyupwardly along the body to a position in which the upper end of the camactuator sleeve engages a downwardly facing shoulder 82 on the actuatorsleeve (FIG. 3), at which time the lower expander portion 63 is elevatedabove the dogs 55, the latter being permitted to contract inwardly andbe located completely out of the internal casing hanger groove 37. Onthe other hand, lefthand rotation of the actuator sleeve 69 will effectdownward movement of the cam actuator sleeve 62 along the tubing hangerbody, shifting its expander portion 63 behind the dogs 55 and expandingthe latter outwardly into the casing hanger groove 37.

The tubing hanger is lowered from the drilling vessel into itsappropriate seating position within the casing hanger 11, is firmlysealed thereagainst, and is appropriately oriented relative to thegroove 28 in the connector 22, and, therefore, with respect to theblowout preventer stack 19 and the guidance system through use of arunning tool 90 connected to the tubing hanger. The running toolincludes an upper sub 91 having a threaded box 92 threadedly secured tothe lower end of a running string 93 of drill pipe, or the like,extending upwardly through the marine riser to the drilling vessel. Therunning tool includes an inner body member 94 disposed in a counterbore95 in the upper portion of the tubing hanger body 39 and having asuitable side seal ring 96 therein sealingly engaging against the innercylindrical wall of the counterbore. The upper portion of the hangerbody 39 includes a circumferential internal groove 97 above itscylindrical surface having a downwardly tapering lower side 98 and anupwardly tapering upper side 99, this groove being adapted to receive asplit lock ring 100 mounted in a groove 101 defined between the innerbody member and an outer guide sleeve 102 the'reabove, which is spacedfrom the lower side of the groove to provide upper and lower guidesurfaces for the split lock ring 100.

The upper portion of the outer guide sleeve 102 surrounds an upper guidemember 103 constituting the upper portion of the inner body structureand threadedly secured to the inner body member 94, this guide memberhaving an outwardly directed flange 104 overlaying the upper end of theouter guide sleeve 102 and extending laterally beyond its periphery. Thelock ring 100 is expandable laterally outwardly hydraulically and islocked in its outward expanded position by an annular cylinder member105 slidable along the inner body member 94. Thus, the annular cylinderis located within an annular space 106 between the inner body member andthe outer guide sleeve. It includes a lower cylinder sleeve portion 107slidable along a lower piston portion 108 of the inner body member, theguide member 103 having a depending annular piston portion 109 alongwhich an upper cylinder sleeve 110 is slidable. An inwardly directedcylinder head 11 1 is disposed in the space between the upper and lowerpistons 109, 108, being slidable along a reduced diameter peripheralportion 112 of the inner body member. The upper sleeve 110 slidablyseals against a suitable seal ring 113 in the upper annular piston, thelower cylinder sleeve 107 slidably sealing against a suitable seal ring1 14v in the lower piston 108, there being a seal ring 115 in thecylinder head 111 slidably sealing against the periphery of the reduceddiameter portion 112 of the inner body member 94.

Fluid under pressure derived from the running string 93 can pass into aradial port 116 between the interior of the inner body member into anupper cylinder space 117 to shift the actuating cylinder 105 downwardlyalong the inner body member, for the purpose of engaging an upperinclined cam face 118 on the split lock ring 100 to expand the latteroutwardly into the inter nal groove 97 in the upper portion of thetubing hanger body 39 and to then shift behind the inner cylindricalsurface 119 of the lock ring to retain it within the hanger body groove97. On the other hand, when the lock ring 100 is to be released from thegroove 97, fluid under pressure is directed from the interior of theinner body member 94 through its side port 120 into the cylinder space121 between the lower piston 108 and cylinder head 111 to shift thecylinder upwardly and out of engagement from the split latch ring 100,allowing the latter to contract from the hanger body groove 97 The innerbody member 94 is movable longitudinally with the top sub 91 of therunning too] 90, this top sub, however, being rotatable relative to theinner body member, because of the provision of a swivel 125therebetween. This swivel is constituted by the external flange 104 onthe guide. member 103 projecting into an internal groove 126 definedbetween a lower upwardly facing shoulder 127 of a clutch member 128surrounding the outer guide sleeve 102, and threadedly secured to thetop sub 91, and a downwardly facing shoulder 129 provided by the end ofthe top sub; Rotation of the top sub 91 relative to the inner bodymember 94 is facilitated by a ball bearing 130 provided between the topsub and the inner body structure. Thus, the top sub has a downwardlyfacing raceway 131 therein opposed to an upwardly facing raceway 132 inthe upper end of the guide member 103, ball bearing elements 133 beingreceived in both raceways. Leakage of fluid between the guide member 103and the top sub 91 is prevented by a suitable side seal ring 134 in theguide member sealingly engaging the opposed inner wall of the lowerportion of the top sub.

The rotary motion of the running string 93 and top sub 91 is transmittedto the actuator sleeve 69 for the purpose of lockingthe dogs 55 in thegroove 37 in the casing hanger 11, or to release the dogs from suchgroove. Such transmission of rotary motion is effected by the.interengagement of downwardly facing clutch teeth 135 at the lower endof the clutch member 128 with companion axially extending teeth 136formed in the upper end of the upper actuator ring 71 secured to theactuator sleeve 69.

An outer orienting sleeve 137 surrounds the clutch member 128, actuatorsleeve 69, the the upper portion of the cam actuator sleeve 62, having alower slot 138 therethrough adapted to receive the outer portion of theorienting dog or key 65, this slot terminating in a downwardly flaringmouth 139 to facilitate passage of the key into the slot. This orientingsleeve is movable longitudinally with the top sub 91 and upper clutchmember 128 by being secured, as by cap screws 140, to an upper orientingsleeve member 141 that extends into a peripheral groove 142 definedbetween an upwardly extending shoulder 143 on the clutch member and adownwardly facing shoulder 144 provided on the top sub. The orientingsleeve has a narrow, vertical groove 145 therein in which an orientingkey or dog 146 is radially shiftable, this key or dog being shiftableoutwardly by a helical compression spring 147 bearing against the base148 of the groove and against the cen tral portion of the dog. Theoutward extent of movement of the dog is limited by engagement of itsupper and lower terminals 149 with companion upper and lower stop plates150 secured by screws. 151 to the orienting sleeve 137, the dog havingupward and downward tapering external surfaces 152 to facilitate itslongitudinal movement past obstructions that it might encounter. The dog146 has a circumferential extent or width conforming to the width of thegroove 28 in the connector 22, to be forced by its spring 147 thereinto.

Because of the swivel connection between the outer orienting sleeve 137and the sub 91 and clutch member 128, the clutch member can transmit itsrotary motion to the actuator sleeve 69, after the orienting key 146 hasexpanded into the connector groove 28, for the purpose of locking andunlocking the dogs 55 in the casing hanger groove 37. However, prior tolocking of the dogs in the groove, the rotary motion of the runningstring 93 and top sub 91 is transferable to the outer orienting sleeve137 for the purpose of turning the latter within the connector 22 into aposition in which its spring pressed key 146 expands outwardly into theconnector groove 28.

When the tubing hanger 10 is to be lowered and set in sealed offrelation in the casing hanger 11, its cam actuator sleeve 62 is firstdisposed in an upward position along the tubing hanger body 39 (FIG. 3),with the upper end of the sleeve abutting the downwardly facing shoulder82 on the actuator sleeve 69, the lower end of the cam actuator sleevebeing in its upper position with respect to the dogs 55. The runningtool 90 is secured to the tubing hanger. 10, the inner body member 94being piloted within the upper end of the tubing hanger body and thecylinder 105 being hydraulically actuated to be shifted downwardly toexpand and retain the lock ring 100 within the upper body groove 97. Atthis time, the clutch teeth 135, 136 are engaged and the orienting key65 is located within the orienting slot 138 in the lower portion of theouter orienting sleeve 137. Accordingly, the tubing hanger 10 has aknown angular relationship relative to the spring pressed orienting keyor dog 146 mounted in the orienting sleeve.

The running tool 90 and tubing hanger 10 are lowered by the runningstring 93 through the marine riser and blowout preventer stack 19 andinto the casing hanger body 11 and casing hanger 12b, until the landingring 41 engages the companion seat 36 in the casing hanger. The runningstring of drill pipe 93 and running tool 90 are then rotated, which willeffect rotation of the actuator sleeve 69, because of the engagement ofthe clutch elements 135, 136 with one another, and also rotation of thecam actuator sleeve 62 in view of the abutting of the upper end of thesleeve with the shoulder 82 on the actuator sleeve 69, the rotationbeing in a right-hand direction. Accordingly, the entire tubing hanger10 is rotated as a unit, this rotary motion being transmitted throughthe orienting key to the orienting sleeve 137, which turns the springpressed dog 146 with it until the latter is opposite the connectororienting groove 28; whereupon the spring 147 will shift the orientingkey into the groove 28, preventing further rotary motion from occurring.However, in view of the know relationship between the orienting dog 65and the passages 29-31 through the tubing hanger body 39, and of suchorienting dog with the spring pressed orienting dog 146, the engagementof the spring pressed key 146 in the connector groove 28 places thetubing hanger body 39 in a known angular relationship with respect tothe connector 22, and, therefore, with respect to the guidance system 15along which the connector has been placed, the connector groove 28bearing a known relationship to the guide posts 17 of the guidancestructure.

Following landing of the landing ring 41 against its companion casinghanger seat 36, and the positioning of the orienting key 146 in theconnector groove 28, the running string 93, top sub 91 and clutch member128 are rotated in a left-hand direction, which will rotate the actuatorsleeve 69 in a left-hand direction. Since the cam actuator sleeve 62cannot rotate, being fixed to the tubing hanger body 39 by the orientingkey 65, and to the connector 22 through the key 65, orienting sleeve137, key 146 and groove 28, the cam actuator sleeve 62 is shifteddownwardly along the hanger body 39, its lower expander portion 63moving behind the dogs or latches 55 and shifting them laterallyoutwardly into the casing hanger lock groove 37 with which they arealigned, bringing the tapered cam surfaces 57 of the dogs intoengagement with the companion cam face 38 defining the upper side of theeasing hanger groove. As more left-hand torque is applied to the runningstring 93, top sub 91, clutch member 128 and actuator sleeve 69, the camactuator sleeve 62 is shifted downwardly to a further extent, the dogsbeing shifted radially outwardly to a further extent. In

view of their tapered engagement with the upper side 38 of the casinghanger groove 37, the lower body member 47 and the tubing hanger body 39are urged downwardly, forcing the landing ring 41 downwardly andinsuring firm leakproof sealing engagement between the seal rings 44 andthe casing hanger seat 36. The cam actuator sleeve 62 remains behind thedogs 55 and insures the retention of the tubing hanger body 39 in itsdownward position locked to and sealed against the casing hanger 11.

The running tool can now be released from the set tubing hanger 10. Asuitable dart is lowered through the running string, coming to restwithin the inner body 94. This dart has a central passage 171 openingthrough its upper end communicating with a side port 172 that, in turn,communicates with the lower port 120 in the inner body member 94,intermediate and lower seal rings 173 on the dart sealing against theinner wall of the inner body member on opposite sides of the body port120. The dart has a longitudinal bleeder passage 174 therein openingthrough its lower end and communicating with another side port 175 thatcommunicates with the upper port 116 of the inner body member, therebeing an upper side seal ring 173 on the dart engaging the inner wall ofthe inner body member 94 above the port 116, the intermediate seal 173engaging the body member below the port to prevent leakage of fluidlongitudinally along the dart. Pressure is then applied to the fluid inthe pipe string 93 which will pass into the lower cylinder space 121 andshift the cylinder 105 upwardly along the body 94 from its positionbehind the split lock ring, thereby releasing the running tool from thetubing hanger body 100 (FIG. 4). This allows the running string 93 to beelevated, elevating the running tool 90 therewith, the upper side of thelock ring 100 engaging the upper side 99 of the tubing hanger bodygroove 97 to shift the ring inwardly from the groove, the clutch teeth135 on the clutch member becoming disconnected from the companion clutchteeth 136 on the actuator ring 70, and the outer orienting sleeve 137sliding upwardly along the cam actuator sleeve 62 and completely off thefixed orienting dog or key 65. The upper inclined surface 152 on thespring pressed dog or key 146 will engage any obstructions thereabove,such as the upper end of the groove 28, and be cammed thereby inwardlycompletely from the connector 22 to move upwardly with the remainder ofthe running tool 90 through the blowout preventer stack 19 and marineconductor or riser 20 to the drilling vessel.

Following elevation of the running tool 90 to the drilling vessel, thetubing strings 180 can be lowered for seating, supporting and locking inthe tubing hanger body 39, in a known manner (FIGS. 5, 6). One exampleof a tubing string arrangement is illustrated and described in theUnited States patent application of Bobby I-l. Nelson and Benton F.Baugh, for Tubing Hanging Method and Apparatus, Ser. No. 868,319, filedOct. 22, 1969, in which tubing 180 is locked in sealed relation to thebody 39 by a ring 181 in a body groove 182.

Following appropriate landing of the strings of tubing in the tubinghanger 10, the marine riser 20 and blowout preventer stack 19 can beremoved and a suitable Christmas tree assembly (not shown) lowered alongthe guide lines 18 and appropriately secured to the casing hanger body39, with the passages in the Christmas tree placed in proper sealedrelation with respect to the individual tubing strings 180. TheChristmas tree is lowered along the guide lines and onto the guide posts17 and will be oriented properly relative to the guidance structure and,therefore, with respect to the passages 29-31 in the tubing hanger 10and the tubing strings 180 depending therefrom into the well bore 14.

In the vent it is desired to release and retrieve the tubing hanger 10,the running tool 90 is secured to the running string 93 with thecylinder 105 in its upper position, this combination being loweredtoward the tubing hanger. The lower portion of the inner body 94 willshift into the counterbore 95 of the tubing hanger body 39, with thesplit lock ring 100 disposed opposite the lock groove 97 in the tubinghanger body. As appropriate dart (not shown) is then lowered through therunning string and into the inner body member 94, which will directfluid from the running string through the upper port 116 into the uppercylinder space 117 and allow fluid to bleed from the lower cylinderspace 121 through the lower port 120, the pressure of the fluid in therunning string being increased to effect downward shifting of thecylinder 105 along the body 94 to engage the lock ring 100 and expand itfully within the groove 97, the lower cylinder sleeve 107 coming to restbehind the lock ring, thereby coupling the tubing hanger body 39 to theinner body member 94 and to the running tool 90. At this time, theclutch teeth 135 on the upper clutch member 128 will mesh with thecompanion clutch teeth 136 at the upper end of the upper actuator ring71. The running string 93 can then be rotated to the right, which willeffect rotation of the actuator sleeve 69 to the right, and, because ofthe threaded interconnection 78 between it and the cam actuator sleeve62, produce upward shifting of the cam sleeve 62 along the tubing hangerbody 39, its lower expander portion 63 being shifted upwardly from itsposition behind the lock dogs 55. When the cam actuator sleeve 62 hasbeen shifted upwardly into engagement with the shoulder 82 on theactuator sleeve 69, the dogs 55 are fully released and the runningstring 93 can be elevated, which will elevate the running tool and thetubing hanger 10 coupled thereto with respect to the casing hanger 11,the dogs engaging the upper cam face 38 on the casing hanger groove 37and being shifted inwardly completely from such groove, the entireapparatus then being elevated to the drilling vessel.

In the event that the actuator sleeve 69 cannot be rotated within thecam actuator sleeve 62 to effect elevation and retraction of the latterfrom its position behind the latch dogs 55, the running tool 90 isreleased from the tubing hanger 10 through use of the dart 170 and theapplication of hydraulic pressure to the lower cylinder space 128, toelevate the cylinder 105 from its position behind the split latch ring100 and the running tool removed to the drilling vessel.

A spacer plate 200 (FIG. 8) is then secured to the lower end of theinner body member 94, which has a diameter conforming to the diameter ofthe counterbore 95 in the hanger body 39. This spacer plate has athickness equal to the longitudinal center-to-center distance betweenthe hanger lock groove 97 and a similar lock groove 97a provided in theflange 71 of the upper actuator ring, which is adapted to receive thesplit lock ring 100.

The running tool 90, with the spacer plate 200 attached, is relowered onthe running string 93, the spacer plate and inner body 94 being movedinto the counterbore region 95 of the tubing hanger body 39, at whichtime the split lock ring 100 will be opposite the actuator ring lockgroove 97a, the cylinder having previously been shifted to its upperposition. A dart (not shown) is then lowered through the running stringand landed in the inner body 94, pressure being applied to the fluid inthe running string and running tool to shift the cylinder 105 downwardlyalong the inner body 94 and expand the lock ring 100 into the actuatorring groove 97a, the lower cylinder sleeve portion 107 then movingbehind the lock ring 100 to retain it in such groove. An upward pull isnow taken on the running string 93 which is transmitted through therunning tool 90 and the lock ring 100 to the upper actuator ring 70,actuator sleeve 69 and cam actuator sleeve 62 threadedly securedthereto. The upward pull must be sufficiently great to overcome theshear strength of the pins 75 securing the shear ring 74 to the tubinghanger body 39, these pins being disrupted and permitting the actuatorsleeve 69 and cam actuator sleeve 62 connected thereto to shift upwardlyto an extent at which the shear ring 74 engages the flange 77 on theupper end of the tubing hanger body 39, at which time the lower expanderportion 63 of the cam actuator sleeve will be shifted from its expandingand holding position behind the dogs 55. Continued upward movement ofthe running string 93 and running tool 90 will then elevate the tubinghanger l the dogs 55, if still disposed in the casing hanger groove 37,being cammed inwardly by the upper tapered cam face 38 of the groove toa position in which the tubing hanger is completely released from thecasing hanger 11. The running string, running tool and tubing hanger canthen be elevated to the drilling vessel.
